java - Loop through all "widgets"/elements in a Activity -

-

i started own android app few days ago since needed mobile application store bunch of data collect in hospital.

i'm pretty new java , android environment, although seems easy understand , similar c++.

anyway, application has bunch of "edittext" , radio buttons , question is:

how can iterate through widgets (edittexts , radio buttons)?

in .net "for each element in container " loop can't seem find way in java/android environment.

note: don't know how many "widgets" exist in activity, since created dinamicaly, others hardcoded , others show if user preferences set

any or hint appreciated.

for (int = 0; < rootview.getchildcount(); i++)   rootview.getchildat(i)

note return view-s, have check @ runtime type of view looking at
